I agree with everything reenum wrote. Peavy and Eaton are the SPs, I would focus on.
But you team, to me anyway, has serious questions marks such as:
Ensberg-He must be platooning for a reason.
Hinske-May never reach his rookie numbers
Baldelli-I don't like at all. Too many Ks.
Thomas-Who knows what you'll get, I doubt a repeat of last season.
As for you arms, Myers is off to a shaky start, as is his entire team. He should be fine. However, Ishii and Okha won't be. See what's on your waiver wire for improvement. I'd rather have a Jerome Williams type SP over either of them.
Also, a) Biddle won't get any save chances, and b) the chances he does get, he will blow about 50% of them. Cordero will close in Montreal before the year is over. Maybe an upgrade there.
See if you can package to improve. It's not a last place team, but one with some holes.
